Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Pylontech P-Combiner-HV-3/6 is a power combination box designed for use with the Force-H-V2 series battery system. This manual provides comprehensive instructions for its safe installation and operation, emphasizing the importance of adhering to safety guidelines to prevent injury, damage, and ensure optimal system performance.

The P-Combiner-HV-3/6 serves as a crucial component in managing the power flow from multiple battery strings to an inverter. The "-3" model is equipped with three input terminals and one output terminal, designed to handle a maximum current of 50A. The "-6" model, on the other hand, features six input terminals and a single output terminal, capable of managing up to 100A. This flexibility allows for scalable battery system configurations, catering to different power requirements.

Function Description

The primary function of the P-Combiner-HV-3/6 is to combine the DC power output from multiple Force-H-V2 battery strings into a single, higher-current output for connection to an inverter. This aggregation simplifies wiring, reduces the number of connections to the inverter, and ensures a streamlined power delivery system. The device incorporates internal fusing for each input string, providing essential overcurrent protection for individual battery connections. A main disconnecting switch is also integrated, allowing for safe isolation of the entire battery system from the inverter for maintenance or in emergency situations. The robust design, with an IP55/NEMA 3S rating, ensures protection against dust and water ingress, making it suitable for various installation environments.

Usage Features

The P-Combiner-HV-3/6 is designed for straightforward integration into a Force-H-V2 battery system. Key usage features include:

• Input and Output Terminals: The device provides clearly labeled input terminals for connecting individual battery strings and a single output terminal for connecting to the inverter. The specific number of input terminals depends on the model (3 for HV-3, 6 for HV-6).
• Disconnect Switch: A prominent disconnect switch is provided on the front of the unit, enabling easy and safe ON/OFF control of the main circuit. This is critical for system startup, shutdown, and maintenance procedures.
• Grounding Point: A dedicated grounding point ensures proper earthing of the combiner box, enhancing safety by providing a path for fault currents. It is crucial to ensure the grounding resistance is less than 0.1 Ω after connection.
• Door Lock: The combiner box is equipped with a door lock, which should be securely fastened after installation to prevent unauthorized access and maintain the integrity of the internal components.
• Cable Compatibility: The manual specifies the appropriate cable gauges for both input and output connections, ensuring safe and efficient current transfer. For the HV-3 model, 6 AWG cable is recommended for the 50A output, while the HV-6 model requires 4 AWG cable for its 100A output.
• Parallel Operation: The P-Combiner-HV-3/6 facilitates the parallel operation of Force-H-V2 battery modules, provided that the selected battery types support this feature. This allows for increased energy storage capacity and power output.
• Clear Electrical Diagram: The manual includes detailed electrical diagrams for both the HV-3 and HV-6 models, illustrating the internal wiring, fuse ratings, and switch configurations. This visual aid is invaluable for correct installation and troubleshooting.
• Environmental Suitability: Designed to operate within a wide temperature range and with high humidity tolerance, the P-Combiner-HV-3/6 is suitable for diverse climatic conditions. Its robust enclosure provides protection against environmental factors.

Maintenance Features

While the P-Combiner-HV-3/6 is designed for reliability, certain aspects related to maintenance and safety are highlighted:

• Fuse Protection: Each input string is protected by a fuse (80A for HV-3, 150A for HV-6), which acts as a sacrificial device to prevent damage to the battery strings in case of an overcurrent event. The manual emphasizes that if any operation requires fuse replacement, all power sources (battery, inverter) must be turned off, and all cables disconnected.
• Safety Precautions for Operation: The manual strictly prohibits opening, repairing, or disassembling the combiner box by unauthorized personnel. Any internal work, such as fuse replacement, must be performed by qualified personnel after ensuring all power sources are disconnected.
• System Shutdown Procedure: For maintenance or any intervention, a clear shutdown procedure is outlined: first, switch off all Battery Management Systems (BMSs), and then switch OFF the Disconnect Switch on the combiner box. This sequence ensures safe isolation of the system.
• Wiring Verification: Before switching on the system, a double-check of all wiring connections is mandatory to ensure there are no reverse connections or incorrect wiring, following the provided electrical diagram. This preventative measure is crucial for avoiding damage and ensuring safe operation.
• Fire Safety: In the event of a fire, the use of dry powder or CO2 fire extinguishers is recommended. Water is explicitly forbidden before all power is cut off, emphasizing electrical safety.
• Disposal Guidelines: The manual includes a reminder for responsible recycling and disposal of the device, adhering to local regulations and prohibiting direct disposal.

The P-Combiner-HV-3/6 is a well-engineered component that enhances the safety, reliability, and scalability of Pylontech Force-H-V2 battery systems. Its design prioritizes ease of installation, operational safety, and clear guidance for maintenance, ensuring a long and efficient service life.
